Insta IH12B Instant Electric Water Heater — 12 kW, Black

The Insta IH12B delivers powerful 12 kW instant heating for quick, consistent hot water without the bulk of a storage tank. Designed for compact wall mounting near the point of use, it’s ideal for apartments, offices, and guest bathrooms that need fast response and a tidy installation. By heating only when you open the tap, the IH12B minimizes standby losses and supports energy-savvy, everyday use. Depending on inlet temperature and available water pressure, a 12 kW rating can comfortably serve a single shower or multiple light-duty outlets*.

The streamlined interface keeps daily operation simple: set a comfortable temperature range, ensure a healthy flow rate, and enjoy stable output for washing, rinsing, and quick clean-ups. Inside, a high-efficiency heating module is engineered for frequent start/stop cycles typical of instant heaters. For long-term reliability, routine care is straightforward — periodically check the inlet screen, remove limescale in hard-water regions, and keep aerators or shower handsets free from blockages.

Safety matters: correct earthing, the right over-current and earth-leakage protection, and proper cable sizing must be provided by a qualified electrician in line with local code. With a modern Black finish and a 2-year warranty, the IH12B pairs style with dependable performance for everyday hot water.
